A clear picture of the Rockies' bullpen targets has emerged in the first week of free agency. They want power arms and are casting a wide net that includes interest in Brian Wilson and Grant Balfour.

The Rockies are aiming high as they try to upgrade a relief corps that struggled dramatically in Rafael Betancourt's absence, finishing with a 4.23 ERA, ranking 28th in baseball. They also like former Detroit setup man Jose Veras and Cleveland sidearmer Joe Smith.

When Wilson was recovering last summer from his second elbow ligament surgery, the Rockies were among several teams that scouted the right-hander. He considered Colorado before signing with the Dodgers, who made the highest offer. The Rockies were encouraged by his strong finish. Pitching effectively in a setup role for the Dodgers, Wilson's fastball averaged 95 mph in October, based on Brooksbaseball.net data, with his cutter at nearly 91 mph, similar to his prime years with San Francisco.

Colorado has a potential closer in Rex Brothers but would like a safety net, giving the Rockies the flexibility to use Brothers as a setup man or to match up against left-handers.

Balfour has received calls from five teams, according to the San Francisco Chronicle. Colorado is a longshot given Balfour's East Coast residency and believed desire to pitch for a proven contender. Balfour recorded 38 saves and a 2.59 ERA for the American League West champion Oakland Athletics last season.

The Rockies continue to chase catcher Carlos Ruiz. The Phillies and Red Sox both have interest in the veteran. If Colorado doesn't land Ruiz, its targets will likely shift to first basemen and outfielders. The list of potential candidates could include Michael Morse.

And St. Louis' Yadier Molina won at catcher over Rosario. ... The Rockies have agreed in principle on a minor-league deal with sidearm right-hander Greg Burke, who will provide spring training depth after spending last year with the Mets and their Triple-A club.
